Have you distributed the release or debug build ? Have you run both builds on your own PC ? Have you tried commenting out different bits of code until you can establish which code is crashing through a process of elimination ?

I try to build both debug and release version on my computer. Everything is Ok. and I try to run both version on the another computer but It occurs "application error"

NOTE: I copy everything that my application dependence on each version

Thanks in advanced

I'm guessing not.

Do you expect me to tell you what the problem is, when I don't even know what framework you're using, your dependencies or what your code does ? Even if I did, I doubt I could answer. Do what I said - comment out parts of the code that might cause such an error ( for example are you creating any COM objects and not checking them before you use them ? ) and then let us know if you find the code that is breaking and still cannot figure out why. I'd love to help, but you're simply not giving me enough information at this stage.

I'm sorry that my information is not enough.

More information
1) My computer has 2 OS (Windows 2000 Advanced Server
and Windows 98 SE). I develop on windows 2000 Advanced Server
and It's work. after this I copy my app and the Dependence
to Window 98 and run it.(it's work)

2) The another computer that I try to run is
Windows 2000 Profressional)

3) My Application (Screen Mate) does as following;
- Windowless
- SetWindowRgn
- Draw Bitmap on Window Region

Thanks a lot for your kindness

Christian Graus30-Jun-02 18:21

Work backwards then - do a build without the draw, see if it crashes. The don't set the region, see if it crashes. Then you can figure out where the problem is.

run-time error if statment

Debug it on the puter where it crashed.
Either install what you need to debug or do remote debugging.

I'm sorry for posting so much code, but since i really dont have any idea why is isn't working I dont know what to show and what not to.

Using the debug tool I have managed to figure out my app crashes at run-time when it executes this line

int int_mode = 0;
CString str_buffer;

if(int_mode == 1) //this is the line that, once executed, crasehes the app

im sure there is something I dont know im doing wrong, so please enlighten me Smile | :)

its been driving me crazy most of the afternoon.

int format_chars(int int_offset, CString input)
{
	int i = 0;
	int a = 1;
	int output = 0;
	int int_mode = 0;
	CString str_buffer;

	while(true)
	{



		if(int_mode == 1) //crashes after this line
		{
			if(input.GetAt(i) == ' ')
			{
				output = atoi(str_buffer);
				return output;
			}
			str_buffer += input.GetAt(i);
		}

		if(input.GetAt(i) == ' ')
		{
			a++;

			if(a == int_offset)
			{
				int_mode = 1;
			}
		}
			



		i++;

		if(i > input.GetLength())
			return -1;
	}
	 

	return -1;
}

Re: run-time error if statment

if(i > input.GetLength())

should be if i >= input.GetLength(); For efficiency you should also put this value into a const int prior to starting your loop.

The reason for >= is that the string is zero indexed, so a string with a length of 5 has only values up to [4].

if string = NULL or empty so CString::GetAt(0) raise assertion.
So first you need check if it not empty and i < CString::GetLength() Mad | :mad:

I need to write a small app that would manage the Java SDK. but i can't seem to get it to work. The problem becomes bigger since i have to deal with the issue of source files and class files. I think it may have to do with directory.

Beginner question: How do I put the open file name in the status bar?

Here is what I have so far in the ChildFrm.cpp file(this is an MDI program).

int CChildFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CMDIChildWnd::OnCreate(lpCreateStruct) == -1)
return -1;

// TODO: Add your specialized creation code here

//create the status bar

m_StatusBar.Create(this);
m_StatusBar2.Create(this);

//width of text we want to display

CRect textRect;
CRect textRect2;
CClientDC aDC(&m_StatusBar);
CClientDC aDC2(&m_StatusBar2);

aDC.SelectObject(m_StatusBar.GetFont());
aDC.SelectObject(m_StatusBar2.GetFont());

aDC2.DrawText("Line #: ", -1, textRect2, DT_CALCRECT);
aDC.DrawText("File: ", -1, textRect, DT_CALCRECT);

//set up status bar big enough to take the text

int width = textRect.Width();
m_StatusBar.GetStatusBarCtrl().SetParts(1, &width);

int width2 = textRect2.Width();
m_StatusBar2.GetStatusBarCtrl().SetParts(1, &width2);

//Initialize the text for the status bar

m_StatusBar2.GetStatusBarCtrl().SetText("Line #: ",0,0);
m_StatusBar.GetStatusBarCtrl().SetText("File: ", 0,0);

return 0;
}

I need to display the open file name in the status bar. Right now, I get:

Line #:
File:

Is there a command for this? I haven't found one.

Thanks for any hints.

Best,

Fill a string (maybe use CString::Format) with the text you want to display ("File:" + filename) and then output that. You're setting the text as 'File:' but nowhere are you specifying that you want the filename itself to be output as well.

This reminds me of that song "My boomerang won't come back". The answer "first you have to throw it".

I've been mucking about with screen savers and need to add multi-monitor support to it. How would I go about it? Surely there needs to be a

C++

Switch (<<Some Message>>)
Case <<some keyword>>:

//Point setting for single monitor
break;
<br>
Case <<other keyword>>:
<br>
//Point setting for multi monitor
break;

Any help would be greatly appreciated.

Use GetSystemMetrics ( or GetDeviceCaps, I forget ) and ask for the size of the virtual screen. Something like SM_CXVIRTUALSCREEN. I'm making this up, but whatever the flag is, that is how I did it and it works great.

I've used the Multi-Screen code from Ben Bryants screensaver to get the points but I need to know the messages that tell the app what setup the client has at runtime. There must be some message or flag that tells the app whether or not there is more than one monitor and for that message I can implement my point variables. Confused | :confused:

I don't think so, I never found it. I just queried the system for the virtual desktop and worked out the screen dimensions from that.
